Type of  Woven Polyester Filter Cloth

We supply two kinds , one is polyester filament yarn filter cloth, and the other one is Polyester staple yarn filter cloth.

  • Polyester filament yarn filter cloth: Long and smooth, good air permeability.
  • Polyester staple yarn filter cloth: Short and not smooth, not good air permeability.

Weave Types

Polyester woven fabrics can have different textures such as plain weave, twill weave, and satin weave.
